strontium is a metal, therefore it must form only positive ions.
The compound formed between strontium (Sr) and chlorine (Cl) is strontium chloride (SrCl2). The formula is determined by balancing the charges of the ions. Sr is in group 2, so it has a 2+ charge, while Cl is in group 17 and has a 1- charge. Therefore, it takes two Cl ions to balance the charge of one Sr ion.
Mg or the element magnesium has only one possible charge of +2. Just a hint but all elements in group 2 have a charge of +2 ie. Be, Ca, Sr...
Group 2 metal ions, also known as alkaline earth metal ions, typically carry a 2+ charge. This is because these metals have two valence electrons that they tend to lose to achieve a full outer electron shell and form a stable cation. Examples include ions like Mg2+, Ca2+, and Ba2+.
The -2 charge ion with the same electron configuration as krypton is the oxide ion (O2-). Krypton has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. The oxide ion gains two electrons to achieve a full valence shell, resulting in an electron configuration of 1s2 2s2 2p6.
I think it's negaive
The strontium ion is called the Sr2+ ion. It has a 2+ charge due to the loss of two electrons from a neutral strontium atom.
This question is quite hard to understand. If you want the full words it's strontium plus. However, the metal strontium is in group II and usually forms Sr 2+. If you want the full electronic configuration it is 2,8,18,8,1 for the unipositive ion and 2,8,18,8 for the dipositive ion. To show this with the full subshell notation is very confusing without being able to do superscripts, but it's the same as krypton for Sr 2+, and [Kr] 5s1 for Sr +.
Naturally-occurring strontium ions typically have a charge of +2. This is because strontium, which is an alkaline earth metal, loses two electrons to achieve a stable electronic configuration, resulting in the Sr²⁺ ion.
Any metal from group 2 (Mg, Ca, Sr, Ba)
Strontium (Sr) would typically form a positive ion, since it is a Group 2 metal that tends to lose 2 electrons to achieve a stable electron configuration. Tellurium (Te) is a nonmetal and would typically form a negative ion by gaining electrons.
The correct formula for strontium sulfide is SrS. It consists of one strontium (Sr) ion and one sulfide (S) ion, which allows them to combine in a 1:1 ratio to form the compound.

Sr(NO3)2 Since strontium ion (Sr2+) has a charge of +2 and nitrate ion (NO3-) has a charge of -1, there must be 2 nitrates to account for 1 strontium making the formula neutral
